A Simple Currency Converter Application:

In this lab, you will design and create a simple currency converter using Swing GUI with

exception handling.

The application should have the following properties:

A Graphical User Interface $($using Swing$)$ that looks something like figure below with JFrame,

Jlabel, JTextField, JButtons, JPanels etc:

Pick $3$ different currencies to convert from US dollars. Associate each JButton with different

currencies to convert and label the buttons appropriately. Please look up the appropriate

conversion rate for the currencies you pick and set it as a final static double $($constant$)$ in

your Currency.java class.

Create a Currency,java class with static methods and static field constants that does the

currency conversion calculations for the currencies you are using in your lab. Your action

Listener will call this class" static methods for the appropriate conversions.

You will need to associate appropriate Actiontisteners to the JButtons so it will perform the

correct currency conversions. When a button is clicked, its action should display a pop up

window that shows the amount in USS converted to the requested currency to $2$ decimol

ploces $($similar to the figure below$)$:

Message

USS $55$ is $75\mathrm{.}90$ in Canadian Dollars.

You will also need to handle exception with the input text field using try$/$catch $-$ such as

when the user enters an invalid number or simply hits return without entering any values $--$

with appropriate messaging $($like the figure below$)$:

Message

Please enter a dollar amount to convert.

OK

Hint: To have the JButtons in $1$ row below the label and textfield, you should put them in a

separate JPanel that you can add to the main panel.
